EXTENSIBLE STOVE-PIPE.

SPECIFICATION forming part of Letters Patent No. 347,150, dated August10, 1886.

Application filed January 14. 1886. Serial No. 188.575. (Modeh) 1'0 allwhom it may concern:

Be it known that I, J OHN SUMERFIELD BEEBE, a citizen of theUnitedStates, residing at Holden, in the county of Johnson and State of 5Missouri, have invented certain new and use ful Improvements inExtensible StovePipes; and I do hereby declare that the following is afull, clear, and exactdescription of the same, reference being had tothe annexed drawings,

1 making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a front elevation of my improved joint,partly in broken section, showing the two sections ofstove-pipe 1connected thereto. Fig. 2 is a detail perspective view of theclamping-sleeve forming the joint; Fig. 3, a similar view of the devicefor drawing the sleeve tightly around the end of the lower stove-pipesection, and Fig. 4 a

cross-section taken on line y y of Fig. l.

The present invention has relation to extensible stovepipes, and theobject thereof is to provide a simple and effective joint thereof,

whereby the stove-pipe can be conveniently lengthened or shortened toadapt it to flues of different heights without the necessity of cut tingthe pipe, which objects Iattain by theconstructionsubstantiallyasshowninthcdrawings, and hereinafter describedand claimed.

In the accompanying drawings, A B represent the upper-and lowersections, respectively, ofa stove-pipe, the ends thereof fitting in asleeve, 0, which forms the joint between the two sections. This sleeveis both contractible and expansible in a direction transversely of itslength, the contraction thereof being attained by mechanical meanshereinafter described, while its expansion is effected by the natural orinherent properties of the sheet metal. To attain this last-mentionedresult, I prefer to slit the metal in a longitudinal direction theentire length thereof, as shown at a, and upon each side of this slit isformed an overlapping flange, 1), extending upon the out- 5 side of thesleeve 0. The flanges b are for the purpose of receiving and acting asguides for similarly-formed flanges 0 upon the inner side and edges of adevice for drawing the sides of the sleeve 0 tightly around thepipe-section B. In the presentinstance I haveshown this device in theshape of a tapering key,D, provided at its upper end with a tongue, (Z,to overlap the inner side ot'the connecting-strip e at the top of thesleeve 0.

When it is desired to lengthen or shorten the stove-pipe, the key D ispressed down by the knob f or other convenient device, and from the factthat the key increases in width in a direction toward its upper end, thelower end of the sleeve 0 is allowed to expand sufficiently to releaseits grip on the end of the pipesection B, and enable the section to bemoved up or down in the sleeve as required, and held in its adjustedposition by shoving up the key, which will draw the lower end of saidsleeve tightly around the pipe-section. can be lengthened or shortenedto adapt it to dues of varying heights without cutting or piercing eachlength.

The bottom joint or section of pipe is connected to the stove, and theother sections of pipe extend from the section connected immediatelywith the sleeve.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is

The combination, with the pipe-joints A B and with the sleeve 0, splitlongitudinally and having the edges turned outward and backward to forminclined flanges Z), and having also the strip 0, of the key 1), formedseg mental in cross-section and having its edges turned inward to forminclined flanges c, to correspond with the flanges b, and the wholearranged for joint operation, as set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN SUMERFIELD BEEBE.
